So as a part of QuickTime, it is normal that Flip4Mac cannot work functionally.

It is because QuickTime loses its ability to support some files when upgrading to Yosemite. One of the most serious problems is some customers find QuickTime with Flip4Mac is not able to work properly with some WMV or WMA files when they upgrade to Mac Yosemite. However, some problems have been troubling Flip4Mac users since Apple released Mac OS X 10.10 (Yosemite).

As time flies, Flip4Mac also develops much more wonderful features like convert files, export files to iOS devices, support HD files and so on. There are Flip4Mac Player (Pro) and Flip4Mac Studio (Pro HD).

Flip4Mac is software used as a component of QuickTime for Windows video audio files playing on Mac OS X system.
